Multi-agent systems and their role in future energy grids (Dagstuhl Seminar 14181)

Authors: Michael N. Huhns, Wolfgang Ketter, Ryszard Kowalczyk, Fabrice Saffre, and Rainer Unland

Published in: Dagstuhl Reports, Volume 4, Issue 4 (2014)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 14181 "Multi-agent systems and their role in future energy grids". A number of recent events (e.g. Fukushima, Japan, and the largest blackout in history, India) have once again increased global attention on climate change and resource depletion. The evaluation of the feasibility of current approaches for future energy generation, distribution, transportation, and consumption has become an important requirement for most countries. There is a general consensus on the need for a fundamental transformation of future energy grids. The development of an information and communication technology (ICT) support infrastructure was identified as the key challenge in the design of an end-to-end smart grid. A multiagent system, with agents located at the edges and nodes of the grid and representing the interests of end-users, distributors, and providers, enables intelligent decisions to be made at each node in the electric power distribution network (grid). The seminar fostered discussions among experts from all relevant disciplines is to develop the foundation for the necessary interdisciplinary solution from engineering, computer science, and business management. The outcome was an understanding and identification of the requirements on the information systems for future smart grids.

10021 Executive Summary – Service-Oriented Architecture and (Multi-)Agent Systems Technology

Authors: Monique Calisti, Frank Leymann, Frank P. Dignum, Ryszard Kowalczyk, and Rainer Unland

Published in: Dagstuhl Seminar Proceedings, Volume 10021, Service-Oriented Architecture and (Multi-)Agent Systems Technology (2010)

Abstract
Service-Oriented Architecture (SOA) stands for a standards-based and technology-independent distributed computing paradigm and architectural style which is especially suited to meet the demands of today’s dynamic business applications. Based on a comprehensive set of independent or at most loosely-coupled and network-available software services SOA is supposed to provide a platform for an efficient and effective publication, discovery, binding, and assembly of these services. Intelligent agents can be regarded as autonomous, problem-solving computational entities with social abilities that are capable of effective pro-active behavior in open and dynamic environments. If the term entity is replaced by service the substantial overlap in interests between both communities can easily be imagined. Nevertheless, right now the main research focus of each community seems to be different. The SOA community concentrates mainly on developing service engineering methodologies. Active topics in the multi-agent systems community are collaboration, self-organization, adaptability, flexibility, pro-activeness, and interoperability. The overlap between those two communities and the fact that they concentrate on different research topics can definitely be seen as a huge chance since it means that each community may be able to benefit from the research efforts of the other. This seminar brought members from both communities together in order to identify such areas of mutual benefit. After extensive general discussions the seminar concentrated on three topics, namely the engineering of complex distributed systems, its governance, and its adaptability and requirements for dynamism.

Adapting Web Services for Multiple Devices: a Model-Driven, Aspect-Oriented Approach

Authors: Guadalupe Ortiz-Bellot and Alfonso Garcia de Prado

Published in: Dagstuhl Seminar Proceedings, Volume 10021, Service-Oriented Architecture and (Multi-)Agent Systems Technology (2010)

Abstract
Mobile devices have become an essential element in our daily lives, even for connecting to the Internet. Web Services have become extremely important when offering services through the Internet. However, current Web Services are very inflexible as regards their invocation from different types of device, especially if we consider the need for them to be adaptable when being invoked from a mobile device. In this paper, we will propose several alternatives for the creation of flexible web services which can be invoked from different types of device, and compare the different proposed approaches. Aspect -Oriented Programming and Model-Driven Development have been used in all proposals to reduce the impact of service adaption, not only for the service developer, but also to maintain the correct code structure. This work has been developed thanks to the support of MEC (contract TIN2008-02985).

An Agent Based Approach for the Decentralised Compensation of Business Processes

Authors: Tim Lessner

Published in: Dagstuhl Seminar Proceedings, Volume 10021, Service-Oriented Architecture and (Multi-)Agent Systems Technology (2010)

Abstract
An automated execution of business processes, composed of Web Services, also requires a reliable error handling and in the case of failures at least parts of a process need to be recovered. One way to enable a forward oriented recovery is compensation which allows to semantically undo effects even "long" time after the process --a long running transaction-- commits. Usually, compensation as for example applied in BPEL (Business Process Execution Language), requires that all compensation steps associated with the business process perform successfully. Also, the conditions for a compensation are not considered and it is not dynamic. In some business scenarios, e.g. a complex production process involving several partners, compensation is a commitment under certain conditions. These conditions in turn can be dynamic and interdependent. Often, a lot of human effort is required to perform compensation. Agents in turn, can enable a decentralised compensation in which agents negotiate a commitment to find a proper compensation strategy. Especially in highly dynamic environment this enables on the one hand a dynamic compensation, and on the other it can support human decision finding in case of failure.

Programming Service Oriented Agents

Authors: Benjamin Hirsch, Thomas Konnerth, Michael Burkhardt, and Sahin Albayrak

Published in: Dagstuhl Seminar Proceedings, Volume 10021, Service-Oriented Architecture and (Multi-)Agent Systems Technology (2010)

Abstract
This paper introduces a programming language for service-oriented agents. JADL++ combines the ease of use of scripting-languages with a state-of-the-art service oriented approach which allows the seamless integration of web-services. Furthermore, the language includes OWL-based ontologies for semantic descriptions of data and services, thus allowing agents to make intelligent decisions about service calls.

Abstract
A description of the current problems of service-oriented architectures and service-oriented computing and how the solutions will come from using agent technology. That is, services will have to become more agent-like in order to succeed fully in the marketplace.
